Default water /top end cleaner

I was at a local cruise the other night, and was telling a mechanic friend about my hard start, when the car is warm. I told him that I was reading on the Forum about top end cleaner , and was thinking about doing it. He told me at the dealership where he works they spray water into the air filter. He claims this really cleans up the injectors and so forth. Besides being a mechanic he owns a Camaro, and a Hayabusa , which he says he uses water on both. Has anyone ever heard of doing this, thanks Jim.

Spray water into the air filter? Wouldn't this just ruin the air filter and hydrolock your engine?

I've used Seafoam on my camaro and vette and have liked it a lot. I was a little disappointed that I didn't get much black smoke out of the vette at first. I drove out to the highway and pulled out in front of some slow moving, on coming traffic and gave it some gas. The car sputtered for a bit which scared me for a sec, then it roared to life and left a huge cloud of black smoke for those 20 cars to enjoy while they were stuck behind the one slow driver, lol.

Yes!!! When I had my '84 vette I use to pour water in the throttlebody while someone would be in the car keeping the rpms up! I poured just a slow trickle in while someone was giving it gas, so it would not flood! Have to say, alot of carbon build up came out of the exhaust, and it ran alot better afterwards! I don't know if I would try it with a C5 though!

I have heard of this being done before by a very "resourceful shade tree mechanic".

I would never let him work on my car by the way.

not through the filter, and you use small amount of water, it brake's carbon loose ( turn's to steam ans expands in the cyl.) i like the new chemical's we have now better

years ago I have done this to remove carbon when octane numbers were low. have not tried it in 15 years. you could prob add it thru the PCV connection.

I've used SeaFoam thru the PCV connection on the side of the throttle body. Watch out for backflow if the engine stalls. I'm not sure what happened, but when I was doing mine the engine stalled and air backflowed into the bottle I had SeaFoam in, and it sprayed all over the place. SeaFoam is a good thing to do if you're installing a catch can, and a good thing to do annually if you don't install a catch can.

6spd98, let me start a little bit earlier. First of all, I wanted to use GM's Top End Cleaner that's usually available at the dealerships part counter. I was in California when I decided to do this, and quickly found that GM's Top End Cleaner was banned earlier this year, but SeaFoam, available at Napa wasn't caught in the ban. Anyway, at Napa it's about $6 a can. I can't tell you how much GM's Top End Cleaner is, but I'd guess $5. Make sure you get the bottle, not the worthless tiny spray bottle.

Thanks Eugene......I know the GM Top End Cleaner creates a lot of smoke, if I tried using it it my neighborhood some one would definitely call the fire dept.-police-and local newspaper . I'll look for SeaFoam next time I pass a Napa store

If you want to use water, the key is a small trickle. Don't use a water hose with a running stream of water.

I used a spray bottle so it shot a mist instead of a stream

Any issues with removing the air filter and using a spray bottle that way? Will it damage the MAF / wires?

I'm sure water works, but with the chemicals you actually try to stall the engine, and then let the chemicals soak the engine for 8 hours or so before restarting it. You'll get a lot of smoke during the initial process, but if you wait for 8 hours, WHOA! Lot's-n-lots of smoke!

Dan, not worth the risk. That MAF has caused me soo many headaches that there's no way I'd mess with it.

Spraying water into the air cleaner will not get anything done inside the injectors. The fuel line is isolated from the air in the engine.

The steam effect is where these top engine cleaner type fixes get their cleaning power from as far as removing carbon deposits. I soaked a carbon coated valve in top engine cleaner for 24 hrs and still couldn't get the carbon off with aggressive wiping with a rag.....the steam/heat is part of the cleaning effect.

here is my more than 2 cents... if you pulled the motor apart, and used a steam gun you would not instantly remove the burnt on carbon.. the process of removing carbon requires a chemical which isn't burnt off at combustion temperatures..it is absorbed by the carbon and causes a chemical breakdwn of the carbon.. the intitial cleaning action is only the surface carbon.. the breakdown occurs over several hours and is slowly and safely burned off .. no chunks of carbon getting stuck on a valve seat. I would never use water on an LS1 motor. The End

Airplanes use water injection, those motors are spotless when they come apart. If it's OK for a plane, it's OK for me.
